E4PA-LS200-M1-N | Omron | Capteur de déplacement ultrasonique

Description

Designed for stable, high-precision distance measurement in demanding industrial environments, the Omron E4PA-LS200-M1-N is a rugged ultrasonic displacement sensor engineered for non-contact object detection and position tracking. Operating at a frequency of approximately 180 kHz, this high-accuracy sensor transmits ultrasonic waves to determine the absolute distance to a target object, independent of the target's color, transparency, or material composition.

The E4PA-LS200-M1-N features dual concurrent analog outputs, providing both a 4 to 20 mA current output and a 0 to 10 V voltage output to ensure seamless integration with modern PLC, DCS, and industrial controllers. An integrated mutual interference prevention function with a fast 34 ms cycle time allows multiple sensors to be mounted in close proximity without cross-talk. Encased in a robust housing, it delivers excellent linearity and temperature compensation for stable operation under fluctuating thermal conditions.

Features

• Wide-range measurement capabilities spanning from 120 mm up to 2,000 mm with a minimal dead band zone of 120 mm.
• Dual independent analog outputs (4 to 20 mA current and 0 to 10 VDC voltage) for versatile controller matching.
• Active temperature compensation maintaining stable measurement linearity of +/-1% FS max across the entire operating range.
• Built-in mutual interference prevention cycle allowing synchronized multi-sensor arrays.
• Integrated protection circuitry, including load short-circuit protection.

Applications

• Continuous liquid and solid level monitoring in process tanks, silos, and open vessels.
• Loop control and tension tracking in paper, plastic, and metal foil winding systems.
• Stack height detection, packaging alignment, and palletizing verification in materials handling.
• Real-time thickness measurement and positioning control in manufacturing and automotive assembly lines.

Installation Guidelines

• Mounting Alignment: Mount the sensor perpendicular to the target surface. If the target surface is rough or uneven, slight angular adjustment may be required to optimize the echo signal path.
• Cabling and Shielding: Use a high-quality, shielded 5-core M12 cable for signal runs. Keep sensor cabling isolated from high-voltage AC power lines to minimize potential electromagnetic noise induction.
• Synchronizing Multiple Sensors: To prevent mutual interference when placing two or more sensors close together, connect the Pin 5 (Sync Line) of each sensor in parallel.
• Environmental Protection: Ensure the transducer face is kept free of heavy dust, water droplets, or ice buildup, which can attenuate the ultrasonic signal transmission. Do not mount directly in the path of strong air currents or high-speed ventilation exhausts.
